Analog clock include the effect of fiber non linearity such as cross phase modulation and the cross talk due to XPM. The expression for the signal MAI and cross talk are derived for a single mode fiber transmission link operating at gigabit per second. Performance results are evaluated 1 Gbps & 10 Gbps with different codes like M-system, gold sequence and pn-sequence to compare their relative performance. The optimum system design parameters are determined at a specific BER (bit error rate).62 pagesenBRAC University thesis are protected by copyright.
